I don't consider this a "dependency issue" at all. These are all
literally separate things; you do not meed smbus(4) and smb(4) if you
just simply want to tie a driver to a feature/device that's on the PCI
bus (e.g. ichsmb(4)).
Besides, does kldload or kernel modules in general have *any* sort
of dependency tree code? I didn't think they did.
Some modules do, some modules don't.
One of the issues here is that there is sometimes a diamond-like
dependency graph between kernel modules, or there is no way to establish
dependency at all.
For example, smb(4) has no idea that ichsmb(4) should be loaded, for the
very reason you point out that smb(4) isn't needed by ichsmb(4); whilst
ichsmb(4) presents an smbus(4) interface in the kernel, which smb(4)
will recognise and attach to, it has no idea that it should get loaded.
Having said that, I thought your plain language explanation of how
things are was excellent and clear.
